My'heater, asillustrated inthe drawing isy f enclosed in a nietalcasing l which may ber eitherfsheet or cast metal'. This casing is provided'with a rear' wall'l'a `anda second rear wall 1b"spaced,inwardly from theformer-,r and" isalso providedy with al front wall; 1c.'

between the walls 1a and 1b. It will be noted, however, that the passage between the walls lol and le may be connected to any other source of air to be heated.

Vithin the casing are positioned in super imposed relation a plurality of fiues 2. These lues are positioned between and supported by the rear wall 1b and the front wall lean'd extend in an upwardly and curved direction,

from the former to the latter connecting the rear passage with the room. TheY lues ex?" tend between and are preferably secured,A at

their lateral sides to the si`de walls 1f and lig.i

are soshaped that all'ofrthem maybe madek from one die and so 'that they maybe nested one within the other. All of the flues are of the same: shape, buty when superimposedone over fthe other 'within the casing, the space between adjacent fines, and intermediate theY rear )and vfront openings thereof, is constricted, as shown in Fig. 2, preventingr free flo'wlof hotgases of combustionfrom the space 'at the rear portion of theh'eater and between adjacent fines,- toward the front space between the tlues, as shown in'Fig; 2. 'These spaces between adjacent'flues, and near the ends of the ogee curves, form longitudinal passages A and B at the rear and front portions of the casing.l These passages are con' nected at the alternate ends of the lines by means of rectangularcut out portions2aV and 2b aty the Vends and cornersof the lues, as shown best in Figs. l, 2 and 3,' thelongitudinal passages at the rear of the heater forming with the vertical connecting passages-or openings 2a, a zigzag passagefor the gases ofcombustion from'thelower portion ofthe' heater to the upper portion. The passages. B form with the verticalipassages or'op'enings 2b similar zigzag passages. Although these,

passages at the rear and forward portion of the` heater are substantially"separate,lthe slight l space between the fines' "at the. middlel portion'of the heater permits the gasesof combustion from the rear passages AQto iiQw. upwardly'toward the front passagesB so als to permit the impinging ofhotgasesof conr-rv Y bustion over substantially vthe vwhole .of the interior surfacesofthe iiuesg .l K, The luesma-y be -made ofsheet; metal plates 2,0 secured together-at their;lends,.byA

end members 2d whichare cast with thel edges;

of the plates 2c cast in place. In the endv erably near the lfront side thereof... Thevr burner, in this instance, is shown mounted on the wall or upper bottom le and receives its supply lof oXygen-fromthe passage between the bottom walls 1d and le. The flame of ythe'burner is directed backwardly so that the greater Vportion of the gases of combustion pass upwardly through the rear vertical passages 2a. ,There is provided in the casing below ,thelowermost iiue. 2 a baffle platel which facilitates the directing ofthe ame backwardly. At the upper -end ofthe ycasing is avstack or duct 5 which communicates saidA ends and theside walls of the casing.v

These spaces or` vertical passages aresepa` rated by spacers 6 which secure the lues tothe;.side'walls and also divide thespacesl at ends or sides so that the gases of combustion cannot v.flow directly into the stack, but i serve as battles for directing the gases of combustion from one horizontal passage B to another around the lateral side or end ot' each of thev 'lues. The spacers or baffles 6 are of substantially' theV curvature ot' the flues. Thus, in this instance, the whole of the end., orlateral sideof the casing at thelateral sidesof the iues are connected insteadA of merely ;throu gh small .vertical passages.

K .Atthe front side of the casing isa perfo` rated grating 7 having perforations forI admittinghot, air from the tlues into the room, At the lower end oi the grating are also `perforations for admitting air from the room into the space between the bottom Wallsld andlefj l., .fjv Though I have shown and described 'a particular construction, combination 'and ar' rangement vof partsand portions, and a cer,- tain modification thereof, I do not wish to be limited to this Vparticular construction, combination and arrangement, nor to the modi# iication, but "desire to include in the scope of my inventio'ntheconstruction, combinar.
